Twnety-one year old Amy Wilson said: "No amount of training can fully prepare us for what we have signed up for, it is going to be the most difficult thing I’ve ever put myself through, but a change in diet and plenty of exercise is a good way to start."

The oldest member of the group Schofield’s managing director Gary Holland, 50, said: "I want to prove a point to all the young whipper snappers in the group and show them that age doesn’t matter I can still keep up with the rest, even if I am getting on a bit."

Also taking part are Dean Fletcher, 35, and Rachel Spode, 33.

The team is aiming to raise more than £2,500. To donate visit Schofield’s website and follow the links.
